Answer: C
Explanation:
Hot air is a lot less dense for a few reasons. Hot air essentially means the particles have more kinetic energy, and move around a lot more. Cold air is dense because the particles move a lot less, have less energy, and are closer together.
The density of the stone is 5 because the formula is mass/volume and the volume is 5 and the mass is 25
Let's write the equation
According to law of conservation of mass .
- Mass of products=Mass of reactants
Let required value be x
Answer:
Equilibrium is the state of balance. Where opposing forces cancel each other out and no changes are occurring.
